There's some info on page 477 of the Isadora 4 manual, which if you don't have it is downloadable from here:

Might shed a little light on what those parameters do.

I have a super wide movie frame, which I'd like to pan horizontally, to show just a portion of the frame at each point in time. I hoped to be able to do this by publishing an X offset of the input in the projector actor and then animating it using Envelope actor, however, it seems that this offset controls the projector's output, regardless of from where I am publishing it –– input or output control of the IzzyMap. Am I missing something, or this is a feature request?

Thanks.

The J5create adapters are connected via usb-c ports. On my machine there are 3.

@charlotte_e

I would also suggest going the GLSL Shader route. LLMs can do pretty well if you feed them the contents of Tutorial 3 here and the guts of one of the existing TT GLSL shaders as an example, so that they can understand the formatting requirements.

I'm trying to avoid too many internal scene triggers, so that each cue is its own scene. Is there an alternative for this?

 The alternative I would suggest is not to break something like this into multiple Scenes. With a Sequential Trigger actor used to start your cues in sequence, it's easy to do what you're describing in a single Scene.

@michel Thanks Michel for the quick and helpful reply ~ will try.

And I want to create an actor that will read the incoming MTC and immediately jump to the correct scene.

 The question for me, is how do you find editing these timecodes to be easiest. I would build your approach around what you find easiest to edit/adjust.

zzy is starting as a background process

 Generally, you just need to kill the task in Task Manager, and restart.
This can happen occasionally if you have other software that conflicts in some way. Very difficult to know what software that might be, perhaps something else creating openGL contexts.

yes i have Nahimic

 If possible, update to Nahimic version 2, the issue was corrected in the new version.
If you can not upgrade, the only solution I know of is to remove/uninstall Nahimic cleanly.

I just tested the latency of a Blackmagic Design Ultrastudio Mini 4K and it was 100ms (6 frames). This was using HDMI 2160p60.

I like to use Companion to send commands, like shutter, to any projector. I then trigger Companion from Izzy. It makes swapping out different brands of projectors a lot easier. I also find if Companion can't control something its not meant to be controlled at all.

With that said, you use the standard method of mutating your inputs/outputs to the expected types. 

 @Aolis 

These User Actors of mine can be quite useful for that: https://troikatronix.com/add-ons/mutator-user-actors/

@dusx

Thanks, Ryan.

It'd just be a stream from an IP Camera on the local network, so I think the OBS / NDI solution will work fine for my needs. 
I'm sure you have better things to do with your time :-)

Hi everyone,

I’d like to share an OSC server and client video patch that we created during an Isadora workshop in Cuba some time ago.

The patch was developed as part of a collaborative learning process, exploring real-time communication between systems using OSC. It’s a simple but practical setup that can be useful for those experimenting with networked video, interactive installations, or remote control between machines.

We also used this setup in The Escapist, a large-scale video projection by my friend and artist Pavel Méndez, presented at the National Museum of Fine Arts of Cuba. I’m also sharing a link so you can check out the project and see how it was used in a real-world context. https://youtu.be/gRqExMF7MdA

I’ve made a small update to make it compatible with Isadora 4, although it was originally created for version 2. The goal was to help students implement video-splitting systems without requiring highly specialized or expensive hardware, since access to technology in Cuba can be quite limited. For this reason, the system was designed to run across multiple basic computers. The system uses a Data Array actor to save parameters. You can export and import these settings as external .txt files, so students only need to import their own media.

It’s nothing super advanced, but I’m proud that it worked and was useful for many students, and I believe it can serve as a starting point for anyone interested in creating something similar. It’s by no means perfect, after all it was developed during a 5-day workshop. I didn’t run into any issues, and neither did my students, but you might encounter some.

Feel free to try it out, modify it, or use it as a starting point for your own projects. If you have any questions or ideas for improvement, I’d love to hear your thoughts! I’m always curious to see how it’s being used, so if you do end up using it, please send me a picture or a link—I’d love to check it out.

Best, Milton

Thanks @Skulpture and @Woland

After exporting several different file and codec combos, I realized that it was actually (maybe) a lag in my hdmi extender, which is old and not HDBaseT. I don't do a lot of this kind of content, so the lag was just much more evident...close ups of actors faces so the audio and video were just out of sync because of the lag.

Or at least that's my current theory. I ordered some new HDBaseT extenders and I'm hoping that will solve the problem. But I am using QT/Hap Alpha for the record.

Thanks, as always!

Jake

 Hmmm I am not so sure. HDBaseT is marketed as zero latency. Unless the hardware is faulty or there are other factors we aren't aware of. Let us know how you get on.

point by point process

 Yes, only the selected points will move, and they all move the same amount. I 'stretch' type move would be a great feature request though. I will add this. 

@skuven here is the current update - Including my new aiming system. Its really shaping up!

@dusx Yes! That would help me considerably if its not too much trouble for you... thanks!
